Part of the engine oil burns out during the lubricating action. So oil consumption is a completely natural process. Well-run engines consume 0.2 liters per 1000 km, Audi calls the maximum allowable consumption of 1.0 liters per 1000 km.

The oil consumption of your Audi 80 depends on the following circumstances:

• Overflowing oil results in high consumption because the crankcase ventilation blows out excess oil.
• Thin oil burns faster than thick oil. Seasonal oil becomes liquid like water when heated, and consumption increases accordingly. All-weather oil remains more viscous; first of all, those who drive long distances may notice a lower consumption of this oil.
• All-season oil that stays in the engine for too long becomes thinner, the higher viscosity grade is “lost”, and the need for topping up increases accordingly.
• A sharp driving style, in addition to increased gas mileage, also increases oil consumption. This is especially noticeable if the new engine is immediately subjected to heavy loads.
• During break-in, the engine needs more lubricant.
• Engine leakage. Check according to the scheme described in the chapter Engines.
• Defect in the engine; e.g. defective sealing gasket (valve stem seal), too large clearance between the valve guide and sealing gasket, defective piston rings

Zero oil consumption is suspect

During winter operation over short distances, it may also be that the oil level between measurements does not decrease at all or even increases. This is absolutely no reason to be happy, because it means that the engine oil is diluted with fuel or condensate. This changing oil must be "boiled" during regular long-distance driving to allow the condensation to evaporate. At the end of the trip, the oil level should be checked, because it will drop significantly due to the evaporation of parts of the gasoline and condensate! For extreme city driving without long distance trips in between, it's better if you change the oil earlier than usual; perhaps already after 3000 km or four months.

In winter, one should reckon with an admixture of gasoline in oil of about 2-3%, and due to the better dosed enrichment of the combustible mixture in our injection engines, when starting a cold engine, less gasoline gets into the oil than in old carburetors.

Correct oil specification

Since relatively long oil change intervals of 15,000 km run the risk of deposits in the oil sump, Audi has issued strict oil regulations.

• Ordinary mineral oil must comply with Volkswagen Standard 50101 (VW-Norm 50101). In this case, it has sufficient cleaning properties to prevent the formation of sediment.
• Oils with good anti-friction properties reduce internal friction in the engine. They must comply with the 500 00 standard (VW-Norm 500 00).
• Only in the event that the oil listed above is not available, you can use all-weather or seasonal oil of the categories "API SF" and "API SG" for topping up.

Hint: factors such as the price of an oil or its origin say nothing about its quality!

Oil viscosity

The fluidity of the oil, that is, its viscosity, must meet the requirements for use in this engine. In doing so, two criteria should be kept in mind:

The oil must not be too viscous, as the starter must be able to crank a cold engine, and the places where oil enters in the engine must be lubricated immediately after starting a cold engine.

The oil should not be too thin, because at high temperatures and engine speeds, the lubricating film may break.

SAE classes

The American Society of Automotive Engineers has classified oils into classes according to their viscosity.

Seasonal oil

These classes start with motor oils from liquid winter (winter) oils SAE 5W, 10W, 15W through the intermediate stage SAE 20W / 20 to viscous summer oils SAE 30, 40 and 50.

The cheapest motor oil used to be seasonal oil. For perfect lubrication of the engine, it must be filled with viscous or liquid seasonal oil according to the season. Seasonal oil is almost impossible to find at gas stations or supermarkets today, but it is still often used in fleets. For use in the Audi 80, it is suitable (and this is the opinion of the manufacturer) only as a temporary solution in a hopeless situation.

All-weather oil

The production of multigrade oil used today is more complex and therefore multigrade oil is correspondingly more expensive than seasonal oil. As a viscosity index improver, it contains long chains of molecules that "swell" when heated and lose volume again when cooled. In this case, the oil can "elastically" adapt to temperatures and cover many viscosity classes. SAE 15W-50 oil corresponds to a viscosity class of 15W at -15°C and a viscosity class of 50 at 100°C.

Problematic with multigrade oils based on mineral oils is the fact that the chains of molecules that improve viscosity decompose over time and in this case the oil becomes less resistant to temperature effects. For this reason, Audi does not permit the use of SAE 10W-30 and 10W-40 multigrade oils in its vehicles during the warm season.

The mid-size car Audi 80 was produced in 1966-1996. The model was equipped with gasoline atmospheric engines up to 2.8 liters and up to 176 hp. either diesel atmospheric or turbocharged engines of 1.6 or 1.9 liters. Based on the fourth generation of the Audi 80, versions of the S2 and RS2 were also produced, equipped with turbocharged petrol engines. All cars of the model had a longitudinal arrangement of the engine, front or permanent four-wheel drive. The Audi 80 has changed four generations, in 1994 a successor to the model appeared - the Audi A4 of the B5 generation.

What kind of oil to fill in the Audi 80 depends on the year of manufacture and the operating conditions of the car.

What kind of oil to fill in the Audi 80 depends on the year of manufacture of the car and the air temperature outside the window. First of all, it is necessary to focus on such an indicator as the viscosity and quality of oil for gasoline or diesel.

What engine oil is better to fill in an Audi 80 engine in summer?

Before deciding which engine oil is better to fill in an Audi 80 engine in the summer, you should familiarize yourself with the basic requirements that apply to engine oils.

The first thing you need to pay attention to is viscosity. If the oil is too viscous, the starter will have difficulty starting the engine. Also, the oil should not be too “fluid”, as at high engine temperatures the oil film will “break”.

There are off-season, one-season and easy-flowing oils. For an Audi 80 car, it is allowed to use one-season oil if its timely replacement is provided. Today, one-season oil is practically not on sale. It was replaced by off-season oil, which is not afraid of temperature changes and can be used both in winter and in summer.

It should be noted that no additives should be used in Audi engine oil. This is considered a vehicle violation.

What oil is better to fill in an automatic transmission (automatic transmission) Audi 80?

Before answering the question of which oil is better to fill in an Audi 80 automatic transmission, you need to know that this technical fluid is rarely replaced. In particular, it is associated with the repair of the gearbox itself. Most often, this happens when oil leaks are fixed. In this case, the oil is drained and completely replaced with a new one. The oil in the automatic transmission is filled in by the manufacturer. It is designed for the entire life of the vehicle. If you need to replace it, it is better to contact specialists.

What kind of oil is poured into the mechanics at the factory (officials) in winter for the Audi 80?

The car's operating instructions indicate which oil is poured into the mechanics at the factory (officials) in winter for the Audi 80.

It is recommended to fill in synthetic engine oil 75W-90. According to the instructions, the oil is filled in by the manufacturer and is designed for a long service life, so there is no need to change it. If such a need arises, you should contact the car workshop.

The Audi 80 is a unique family of vehicles that announced itself with the first models more than two decades ago, and is still popular today. This series of cars is called legendary, as it is not inferior in terms of reliability and running criteria even to some cars of modern production. Even when purchasing with significant mileage and age, the car owner, with proper maintenance, can be sure of its long service life. One of the main criteria for car care, regardless of its age and status, is the maintenance of the motor in the form of a timely replacement of the lubricant in the unit. In this article, we will tell you how the oil is changed on the Audi 80, what type of lubricant needs to be filled in, and how often it needs to be changed in order for the car to serve "faithfully" to its owner for many more years.

How to change the oil in an Audi 80 engine.

Replacement frequency

The fact of necessity is known to everyone, even inexperienced, novice drivers. And if professionals with an impressive driving experience can determine the need for a fluid change even by the behavior of the car on the road, for beginners in this matter, the question of when to perform engine maintenance is more than relevant.

According to the recommendations of the automaker, the optimal oil change for the Audi 80 is once a year, or after the car has run fifteen thousand kilometers from the last change. However, professionals call this time interval critical, recommend sticking to it only in cases where the car is operated in ideal conditions, which cannot be said about modern urban driving modes.

In practice, the performance of the oil depends on such negative factors as traffic jams and unforeseen stops, engine loads, regular vehicle weight overloads and adverse climatic conditions, and the quality of the liquid poured into the unit. Based on these negative domestic operating criteria, experts advise in the Audi 80 engine when using all-season motor oil at least once every four months, seasonal lubricants should be changed twice a year - in autumn and spring.

What engine oil is better to fill?

Which oil to choose for the Audi 80 engine is a question that often baffles even experienced car owners. A huge range of products, a variety of small manufacturers and global suppliers, types and classes of oils - not everyone can figure it out on their own. And to all this, a variety of engine modifications is added, differing in volume, horsepower, and fuel. The best solution to the problem in finding the answer to the question of which oil is better to fill in the Audi 80 engine is to study the manufacturer's instructions for transport, which necessarily indicate the most suitable lubricant for each type of motor.

First, let's figure out what kind of oil to pour in the Audi 80 B3. If you are the owner of the Audi 80 B3, which were produced before 1991, then you need to focus on the following parameters:

1. Viscosity coefficients according to SAE for the all-weather period should be 10 or 15W30; for models of the latest years of production, motor oil with.
2. For the winter version, a lubricant with criteria of 5 or 10W is considered the best option for a car oil.
3. The summer version must correspond to a viscosity of 20 or 25W
4. According to the API class, the Audi 80 engine oil is suitable with the SG category for gasoline modifications and CD-II for diesel units.

Mostly hydrocracking or mineral-based motor oils are poured into Audi 80 B3 engines; the use of pure synthetics is considered an inappropriate waste of money, given the age of the car. In this case, it is recommended to use products under the brands Lukoil, Rosneft, Total, Valvoline or Kixx, which comply with the tolerances and specifications from the manufacturer.

A newer version of this series of cars is the Audi 80 B4, which was produced from the beginning of 1991 until 1996. Consider what kind of oil to fill in the engines of these cars:

1. The API standard for gasoline versions remains the same - SG, with the exception of the 1996 model year, with a requirement from the manufacturer for an oil class of at least SH and CF-4 for diesel. Diesel engines prior to 1996 must be filled with a CE grade lubricant.
2. SAE viscosity standards are the same as the previous version for B3 motors, with possible minor deviations depending on the prevailing climatic conditions of the machine.

In the units of the Audi 80 B4 models, the manufacturer recommends pouring predominantly semi-synthetic fluids or mineral-based lubricants, and hydrocracking is also allowed in all versions except for the 1996 release. As you can see, the solution to the question of which oil to pour into the Audi 80 engine varies directly from the engine modification that the vehicle is equipped with, and the most correct answer to it can be found in the user's operation.

And one more important point. Today, a variety of cutting-edge additives are very popular, which are added to the engine to increase its running and operational means. The manufacturer in relation to the Audi 80 motors categorically prohibits their use.

Engine oil volume

The displacement required for, as well as its optimal form, depends on the modification of the motor. Depending on the technical features of the engine and the year of manufacture of the car, the volume of oil in the engine, including additional costs for the oil filter, is from three to five liters. The exact information on the variation of the Audi 80 engine can be found in the instructions from the manufacturer for each specific option. It is also important for drivers how much oil to fill in the unit, and what criteria of the lubricating fluid are considered the norm. This issue is more than relevant, since during operation the vehicle needs regular checks of the oil level and topping up to the norm.

The manufacturer regulates the control of the oil level at each refueling of the vehicle. Only after you have made sure in practice that the oil consumption is small, you can reduce the number of checks, control the level approximately every five hundred kilometers traveled by the car.

Checking the oil level should be carried out in accordance with the following regulations:

1. Check the level after a slight stoppage of the machine, so that the oil drains from the internal surfaces of the motor, which will allow you to get the correct data.
2. Pull the dipstick out and wipe it dry with a clean, lint-free cloth. Insert the dipstick into the control opening to the limit and remove it again - evaluate the level.
3. Oil criteria that are midway between the minimum and maximum limits are considered normal. If the oil is closer to the minimum value, top up. The approximate volume of oil between the minimum and maximum criteria on the dipstick is one liter.

Accordingly, when buying oil, try to purchase it with a small margin so that you have leftovers in case you need to top it up during operation. The most profitable offers on the market are five-liter containers, which are advisable to buy from a position of economy.

Preparatory stage

Before embarking on an independent oil change, it is important to stock up on the tools and consumables necessary for this procedure. Purchase car oil in advance in sufficient volume for the procedure, and also do not forget to purchase an oil filter at a car dealership, preferably an original one, which is advisable to change with each lubricant change. Additionally, it is necessary to purchase a new sealing washer for the oil drain neck, in case the old part is deformed.

From the tools you will need car keys with heads of different diameters, a special puller for dismantling the oil filter and a funnel or oiler for the convenience of pouring fresh liquid into the oil filler opening. When draining the oil, you will need a waste container with a capacity of at least five liters, as well as protective clothing and clean rags for cleaning parts.

Since the dirtiest work is done from the bottom, consider the possibility of doing work in a garage with a viewing hole or look for a place equipped with a flyover. Some car owners perform the task by lifting the car with the help of jacks, however, it is very inconvenient and dangerous to drain the oil under such conditions, since you will have to work on a warm engine and there is a risk of burning yourself while draining it. When all the preparatory work has been completed, you can proceed directly to replacing the car oil in the Audi 80 power unit.

Car oil change: the subtleties of the procedure

Changing the oil in an Audi 80 engine is a simple, however, time-consuming procedure that requires special care and assertiveness from the performer. When doing work, especially if this procedure is performed for the first time with your own hands, it is important to follow the instructions steadily, perform tasks in turn, taking into account all the nuances that will be many in the replacement process.

Step-by-step instructions for changing the oil in an Audi 80, regardless of engine modification, are as follows:

Summing up

The procedure for changing the oil in the Audi 80 power unit is quite feasible at home, garage conditions. Even a technically inexperienced person, following the manual and having the desire to achieve an effective result, will be able to perform this task without much difficulty on their own. The advantage of self-lubricating is significant savings on the services of service station workers, acquiring new experience in interacting with your vehicle and confidence in the quality of the work performed.

Follow the recommendations of the car manufacturer, do not ignore the need to change lubricants, choose motor oils that meet the requirements for the car, and your vehicle will be your indispensable and reliable friend for many years to come.
